SPECIFICATION
1.
AC High Voltage Test Kit (100 kV)
(1)
The unit shall be suitable for testing aerial bucket trucks & with 50-kV tap with doubled output current for
testing bucket liners
(2)
It shall have a built-in four-range output current meter with guard circuit
(3)
Four-range output kilo voltmeter accuracy of which shall be unaffected by sample loading
(4)
High-speed over voltage and over current trip-out for holding test voltage reading at instant of trip-out
(5)
Output signals shall be provided for both voltage and current meters, on all ranges, to permit external recording
of test data.
(6)
Zero-start safety interlock system with provision for external safety interlocks and warning lights
(7)
The Control Unit & High Voltage units shall be separate with a minimum length of 15ft/4.5 meters for the inter
connection cables to ensure operator safety.
(8)
Accuracy: ±1% of full scale, +LSD
(9)
Peak-sensing kilo voltmeter circuit, shall be calibrated in rms for a pure sine wave, for overcoming metering errors
caused by power-line waveform distortion.
(10)
Adjustable over current and over voltage protection, with trip levels variable from 10 to 110%, to provide high-
speed trip-out of test voltage if either limit is exceeded due to high-voltage breakdown or other causes.
(11)
Digital test timer, shall be provided as standard and shall display both preset test period and elapsed test time in
the range of 0 to 99.99 minutes. It shall automatically control motorized voltage regulator and permit more
uniform test cycles.
(12)
Hold circuit shall freeze indication of test voltage and time when a tripout occurs. This relieves the operator of
continuously monitoring test status.
(13)
Ramp and dwell control shall have motorised voltage regulator systems & shall permit test voltage ramping from
zero to a preset voltage stop level. Dwell time at the voltage stop level is controlled by the test timer. At the end
of the dwell time, voltage shall automatically be ramped down to zero, Light up TEST COMPLETE indicator and
then de-energise high voltage. This capability ensures a uniform test cycle and frees the operator to perform
other functions.
(14)
EMERGENCY HV OFF button shall be provided. Provision for external
test-area interlocks & warning
lights
shall be provided.
